Sharks are creatures that many of us imagine being cold-blooded killers. It is hard for us to picture them as needing to sleep, much less doing so in a way that would be familiar to us. And yet, sharks have some unique sleeping patterns that we can all relate to.

While humans spend large amounts of time inside, sharks spend most of their lives in the water. Sharks are creatures of the sea and can be found at all depths, from the shallow coastal areas to the deep ocean trenches. While it is popular to speculate that sharks do in fact sleep, researchers cannot find evidence of this.

In addition to breathing slowly, evenly, and deeply like mammals, these fish-eating machines also slow down their brains and muscles so deep that they’re nearly as inactive as a human hibernating in winter. We call this state of torpor (sleep) daily torpor.

Sharks are fish with a cartilaginous skeleton and five to seven pairs of gill slits. There are at least 400 species of sharks. Sharks have an extra hole called spiracle on the sides of their heads above the eyes. Their bodies are covered with tough, protective scales called denticles instead of true skin. Sharks do not have any bones, only cartilage and a spine which is flexible and moves like a coil spring. The vertebrae of a shark act as shock absorbers providing leverage for moving the body forward.
